5 reviews for Azathioprine (Imuran)
Imuran contains Azathioprine.
Azathioprine is an immunosuppressant. It calms an overactive immune system in conditions such as rheumatoid arthritis, inflammatory bowel disease and lupus, and helps prevent organ rejection after transplants.
What is it used for?
- Preventing organ transplant rejection
- Crohn's disease and ulcerative colitis
- Rheumatoid arthritis, lupus and other autoimmune conditions
- Autoimmune hepatitis
How does it work?
Azathioprine is turned into substances that slow the growth of immune cells, which reduces the immune system's attack on the body.
This information is written in simple words to help you understand this product. It does not replace advice from your doctor or pharmacist.
Read these points before you start. If any of them apply to you, talk to your doctor or pharmacist first.

- Swallow the tablets whole. Do not crush or break them. Wash your hands after handling.
- The dose depends on body weight, often 1 mg to 3 mg per kilogram a day.
- It can take 2 to 3 months to work fully.
If you miss a dose: Take it as soon as you remember, unless it is nearly time for your next dose. Never take two doses at once.

To check your blood cells, liver and kidneys, and sometimes the level of medicine in your blood, so any problems can be caught early.
- QCan I have vaccines while taking Imuran?
- A
Most non-live vaccines, like flu and COVID-19, are recommended. Live vaccines should usually be avoided. Always check with your doctor.
- QWhat should I do if I get an infection on Imuran?
- A
Contact your doctor straight away, even for something that seems minor, like a fever or sore throat. Infections can become serious more quickly when your immune system is lowered.
